Question

49; can vary by 8.1% find the range of allowable values based on the given information

Answer 1

Explanation:

First we have to find the 8.1% of 49:

$49\times\frac{8.1}{100}=49\times0.081=3.969\approx4$

The range of values is 49 - 8.1% to 49 + 8.1% so:

$\begin{gathered} 49-8.1\text{ \%}=49-4=45 \\ 49+8.1\text{ \%}=49+4=53 \end{gathered}$

Answer:

45 to 53
